Patented Jan. 19, 1932 UNITED STATES PATENT" OFFICE RALPH OI CLEVELAND, OHIO,-ASSIGNOR OF FORTY-FIV E 01V E-HUNDBEDTHS '10 BERT I. KENT, OF CLEVELAND, OHIO CARTON Application filed February 8, 1980. Serial No. 425,391.

This invention relates to cartons having pouring spouts therein.

It is one of the objects of the invention to provide a folding carton of the usual rectangular shape, that is commonly used for packing granular, powdered or other non-liquid materials that may be poured, in which the pouring spout is formed within the limits of the ordinary blank that is now used to make a similar carton without a pouring spout, so that the provision of a pouring spout will not require the use of any additional material.

A further object of the invention is to pro vide a carton with a relatively large pouring spout that is adapted to pass lumpy materials.

It is a further object of the invention to provide a pouring spout device, of such construction, that it may be incorporated in a relatively narrow carton and provide an opening of substantially the full width of the carton so as to permit the insertion of a spoon or other implement for removal of some of the contents.

A further object of the invention is to provide a carton, of the type referred to, in which the pouring spout may be formed therein in connection with the operation of cutting out the blank, so that no additional blanking operations are required. Y

A further object of the invention is to provide a carton with a pouring spout device of the kind referred to, that is so formed that the carton may be manufactured on the equipment that is now used for manufacturing similar cartons, without pouring spouts, and which may be packed and sealed on the usual automatic packing and sealing machines that are now used and not require any special equipment for that purpose.

It is a further object of the invention to provide a carton with a pouring spout, of the type referred to, that will be devoid of externally projecting parts, that may be conveniently and quickly opened, and that may be readily closed after it has been opened.

Other objects of the invention and the fea tures of novelty will be apparent from the following description taken in connection with the accompanying drawings, of which: Fig. 1 is a plan view of a blank for forming a folding carton embodying my invention;

Referring to F ig. 1 of the drawings, the blank from which the carton is made is formed from paper stock, in the usual manner, by means of dies which score the blank along the lines 10, 11, 12, 13, 14 and 15 these score lines defining the sides 16, 17, 18 and 19 of the carton. A sealing strip or glue lap 20 is left along one edge of the side 16 and may have extensions, such as 21 at its opposite ends. When the carton is assembled, the strip 20 is glued to the inner surface of the side 19, along the edge 22, and the extensions 21 are glued to the inner surfaces of the flaps 23 and 24. One end of the carton is formed by the flaps 23, 25, 26 and 27, these flaps being folded into overlapping arrangementand glued together in the usual manneri Some of the surfaces of the flaps, to which the glue or adhesive is applied, are indicated by stippling, in Fig. 1.

The other end of the carton is formed by the flaps 24, 28, 29 and 30, but these flaps are ing the end of the carton.

specially formed to provide the pouring spout device which will now be described. The flap 29 is notched, as indicated at 31 and 32, to form a tongue 33 and, when the carton is assembled, the end of the tongue 33 and the points 34 overlap the end of the flap 24, as indicated in Figs. 4 and 5, so as to be supported thereby.

The flap 30 is provided with an opening 35, preferably of rectangular shape and slightly wider than the tongue 33, so as to permit the tongue to be withdrawn through this opening. The opening 35 is enlarged on one side, as indicated at 36, to give access to the end of the tongue 33, so as to facilitate the withdrawal of the latter. The edge 37 of the opening 35 is arranged to register substantially with the base of the tongue 33 so that the latter may be bent over this edge in being withdrawn, as shown in Fig. 2.

The flap 28 is provided with crease lines 38 and 39 which, when the end is sealed, register substantially with the edges 40 and 41, re spectively, of the opening 35 and is further 1 provided with cut lines 42 and 43 which are arranged at right angles to the crease lines 40 and 41 and register substantially with the edge 37 of the opening 35. This flap is also provided with the perforated lines 44 which extend from the inner ends of the cut lines 42 and 43, to the points 45 which register substantiallfi with the corners 46 of the opening 35. A perforated line 47 connects the points 45 so that a substantially triangular removable portion 48 is formed by the perforations 44 and 47. The flap 28 also has an opening 49 positioned along the line 47 so as to give access to the edge of said triangular removable section.

In assembling the carton, the flap 24 is first folded into position, in the usual manner, as indicated in Fig. 4. The flap 29 is then folded in and, according to the mode of operation of a certain type of automatic sealing machine, both sides of the flap 30 are provided with adhesive and this flap is then folded down over the flaps 24 and 29, as indicated in Fig. 5. The flap 28 is then folded over the flap 30 and the several flaps are pressed into sealing arrangement, thus clos- It will be noted that the removable section 48 has its wider end arranged to overlie the portion of the flap .30 on either side of the opening 36 so that this removable section will be firmly supported at these points.

When it is desired to open the carton, the thumb nail or a suitable instrument is inserted in the opening 49 and beneath the edge of the removable section 48 and the latter is torn out. This exposes the tongue 33 and the thumb nail may be inserted under the end of this tongue and it may be withdrawn to the position shown in Fig. 2. In withdrawing the tongue 33, the wings 50 and 51 are swung outwardly to the position shown in Fig. 2 and thus form the sides of a pouring spout, of which the tongue 33 is the bottom.

In the form of the invention illustrated in Figs. 6 to 11, inclusive, which I consider preferable to the construction previously de scribed because it provides a stronger sealed end, the blank is substantially the same as the blank previously described with theexception of the flaps 52, 53 and 54. The flap 53 is provided with a tongue 55 and when the carton is assembled, the end of this tongue overlaps the end of the flap 56, as best seen in Fig. 9. The flap 54 is provided with a U-shape opening 57 which forms a tongue 58 that is secured on the tongue 55 when the end is sealed (see Fig. 10). The flap 54 is also provided with an opening 59, which is zpaced from the opening 57 to form a bridge The flap 52 is provided with cut lines 61 and, bridging the space between the inner ends of the lines 61, but spaced slightly therefrom, there is a cut or perforated line 62. Running at right angles to the lines 61 are the crease lines 63, and the perforated lines 64 extend from points adjacent the inner ends of the lines 61 to the points 65, at the ends of the crease lines 63. A line of perforations 66 extends between the points and another perforated line 67 is arranged about mid-way between the lines 62 and 6 A out line 68 extends from the line 66 and when the outer flap 52 is folded over and sealed to the fiap 54, the line 68 is arranged over the opening 59.

In assembling the carton, the flap'54 may be provided with glue or other adhesive, on its inner and outer surfaces, and will, therefore, be secured to the inner flaps 53 and 56. The outer flap 52, being sealed over the flap 54 will have the section bounded by the lines 62, 64 and 67, secured on the tongue 58. The lines 64. 66 and 67 define a removable section 69 which will overlie and be secured on the bridge 60. The portion of the removable section 69, adjacent the line 67 will also overlap and be supported by the end portion of the tongue 58 so that, notwithstanding the various cuts and perforations in the flap 52. the portions will be firmly supported and secured in position.

When it is desired to open the carton. the portions of the flap 52, on opposite sides of the line 68, are depressed into the opening 59 which will give access to the edge of the section 69. that is formed by the line 66. The section 69 may thus be easily torn off to expose the end of the tongue This tongue may then be grasped by the finger and withdrawn through the opening 57 and, in being thus withdrawn, will swing the wings 70 and 71 outwardly to the position shown in Fig. 7, thus forming a pouring spout and also ICS will permit the insertion providing a relatively side opening 72 which of a spoon into the carton.

When it is desired to close the end of the carton, it is only necessary to push the tongue 55 back to its original position, and this will v permit the wings and 71 to spring back to substantially the position shown in Fi 8. It willbe observed from Figs. 6, 8 an 11 that the lateral edges of the tongue 58 project beneath the wings 70 and 71 when the flap 52 is sealed over the flap 54, and the wings 70 and 71 are thus secured to and supported by the tongue 58 so as to provide a relatively strong construction that will be capable of withstanding any ordinary stresses that the end of the carton may be subjected to in transportation and the usual handling.

The constructions described and illustrated provide a carton with a pouring spout that adds little or no cost to the plain carton and yet the end of the carton can be thoroughly sealed and conveniently opened and closed when desired. The construction is especially adapted for relatively narrow cartons as it makes it possible to provide a pouring spout of only slightly less width than the narrow dimension of the carton.
